"We need to have some serious discussions about diversity and get some flavor up in this," Lee said. "This industry is so behind sports it's ridiculous."

The filmmaker praised Academy of Motion Picture Arts and Sciences president Cheryl Boone Isaacs for "trying to do something that needs to be done." Earlier in the evening, Isaacs called on the industry powers in attendance to take action toward "recognizing and embracing a broad cross-section of talent." She also announced the academy's new five-year plan to improve diversity in its staff and governance.

Cate Blanchett and Laura Linney each paid tribute to Rowlands, calling her a trailblazer and inspiration. The 85-year-old actress, whose career spans six decades, received her Oscar from her son, Nick Cassavettes, who directed his mother in 2004's "The Notebook." He noted that the award was "the first Oscar in the family."

Looking lovingly at the golden trophy, Rowlands thanked the academy governors for "introducing me to this fine fellow."

Reynolds was recognized for her decades-long commitment to various charities, including the mental health organization she founded, the Thalians. Her granddaughter accepted Reynolds' statuette.

A live band played throughout the evening, and there were two musical interludes: Zooey Deschanel performed the Oscar-nominated song Reynolds sang in 1958's "Tammy and the Bachelor." Aloe Blacc sang "A Change is Gonna Come" as part of Lee's introduction.

Other famous faces at the starry dinner included Johnny Depp and wife Amber Heard, Daniel Craig and wife Rachel Weisz, Will Smith, Ice Cube, Mark Ruffalo, Quentin Tarantino, Saoirse Ronan and Michael Caine. Portions of the untelevised ceremony may be included in the 2016 Academy Awards telecast.
